Application filed-December 5, 1.301.A I Seriallo. 84,805. o model.)

To all whom it may concern.: l Be it known that I, ARTEUREHUTCHIN- SON,a citizen of the United `States', residing at Waynesboro, in the countyof Franklin and State of Pennsylvania, havelinvented certain v new anduseful Improvements in vBrine-Cooling or refrigerating apparatuscommonly ers, of which the following is a specification.

My said invention relates to'that class of machinery known as coolers,and applies more particularly to that part of an ice-maklmown as abrine-coolerf. and it consists in vcertain novel arrangements in theform and construction of such part, whereby great economy is secured inthe operation of the device and also in the space required for itsaccommodation in the plant, all as will be here- .inafter more fullydescribed and claimed.

The accompanying drawing, whichforms a part hereof, and on whichsimilarreferencenumerals indicate similar parts, represents one of myimproved brine-coolersw partly in section and partly in elevation, itscentral portion being broken out in order to permit the parts to beshown on a larger scale.

Said apparatus consists of a coil of three pipes concentrically arrangedand connected by suitable iittings through which communication isestablished from one pipe to its corresponding pipe iu the adjacentseries and at the top from the outside pipe to the inside pipe of thecoil. The several fittings are connected byItongue-and-groove jointscontain- -ing suitable packing, whereby the joints areall renderedperfectly tight by meansof theA various suitable clamping-bolts, asshown, or

any suitable character of jointor fitting to accomplish the purpose maybe used.

I have marked the center pipe 1, the middle pipe 2, andthe outside pipe3. A foot or base 4 at one end and 5 at the other end support theapparatus. Pipe 3 screws into or is otherwise secured in the inner endsof ittings 6,which are hollow and have smaller apertures at their outerends, within which are tightly fitted the ends of pipes 2. A secondfitting? is secured outside iitting (i, having a stillsmaller aperturein its Outer end, within which the end of the center pipe 1 is tightlysecu red. Except at the inlet and discharge ends a third fitting S issecu red over the ends of said center pipes, connecting one to the next.Communi- .lis'hed through fittings 6 at alternate ends of ,the pipes andbetween the next spaces through is formed hollow and connected with thelower 4 fitting 6.

cation from the space between the pipes 2 and 3 in one series 'of pipesto the next is estabthe ittings 7 and between the center pipes throughthe fittings 8. At the lower end the brine-inlet is provided throughbase 5, which The ammonia-inlet is established through a fitting 9 onthe Outer end of the lower fitting 6 and the brine-outlet through '.Y afitting 10 on the Outer end of said fitting 9, i, with which the lowercenter pipe communicates. At the top of the apparatus a fitting 11 isattached to the outer'end of top fitting 6, "which f contains a wayleading from the space between pipes 1 and 2 for the ammonia- Outlet andalso'a way communicating with the center pipe and leading upwardly. Are-V turn-bend fitting 12 is mounted on the top Of the uppermost fitting6 and said itting 11, having a way which joins the outlet from saidfitting 6 with said way in fitting 11, which communicates with centerpipe 1, a communication between the space outside of the pipe 2 towithin pipe 1 being thus established at this point.

The operation is as follows: The brine or othermaterial tobe cooledisadmittedthrough the space between the pipes 2 and 3 and iiows tion,when it passes through the return-bend through said center pipe in theseveral secwhence it is discharged through fitting 10 and suitable pipes(not shown) to the freezingtank or other part of the apparatus where itswork is to be done. The ammonia is admitted through inlet 9 to spacebetween pipesl and 2 and flows back and forth until it is dischargedthrough outlet 11 at the top, to be carried through appropriate pipes(not shown) to the storage-tank, as usual. The brine, r frigeratingagent, or whatever material is be cooled is thus admitted at its highesis admitted at its lowest temperaturean I flows in the same directionwith said ammo;

vedete fa through a channel surrounding the pipe mtaining it until thepoint where said ammonia is discharged 1s reached. It will thusdischarge-opening from the central passage, and a ittin g at theopposite end which contains a discharge-opening from the intermei"'positely thereto be seen that the two agents are rst brought 7o atooperative relation with each other at the widest difference intemperature, the result being that the comparatively warm brine at oncesets the ammonia to boiling or evaporating or expanding, which operatesto rapidly absorb the heat from said brine, raising its own temperatureand lowering the temperature of said brine, with the result that -whenthe point of ammonia discharge is reached at the top of the apparatusthe temperatures of the two agents have been nearly equalized or theirequalization approached. s -'Ih-e brine or other substance being cooledf now turns into the center pipe 1 and returns to the lower section ofthe coil within the iuchannel containing the ammonia, iowing opand beingconstantly brought v'against ammonia of a decreasing tempera- Ilture,which results in its temperature being lrapidly lowered by theabsorption of the am- 5 monia of the heat therein, until at itsdisiWcharge-point it nearly approaches in tempera- 'ture that of saidammonia when introduced diate passage, and a bend or way connecting theoutside pipe or passage of the coil with its central pipe or passage,whereby the cooling agent is introduced at one end of the coil and flows.in a continuous direction through the intermediate passage therein andis discharged at the other end, and the uid to be cooled is introducedat the same end of the coil with said cooling agent and flows in thesame direction therewith in a passage in the coil on one` side of thecooling agent and at the opposite end passes into another passage ofsaid coil on the other side of said cooling agent and from thence owsoppositely from said cooling agent and is discharged at the same endwhere introduced, substantially as set forth.

2. A brine-cooler having three or more channels one within the other, anouter ehan nel being -connected by a bend or by-pass with an inner-channel at one end of the coil, the inlet to the one channel and -theoutlet to the other channel being at the same end of into the apparatus.

' `finuous passage-ways By this arrangement, with the brine flowing onboth sides of the cooling fluid all of its power of absorption isutilized and none allowed to waste, and the best possible results aresecured with the least possible quantity of ammonia. 'lhe arrangementalso admits zof a great amount of 5 cooling surface in a small space,thus not ionly securing economy in the use of material,

but in space required for the accommodation of the apparatus, both lofwhich are of great limportance.

While I have described the flow of iiuid as from bottom to top and thenback, it will be understood, of course,

self to this particular arrangement, but consider m'y invention as broadas dened in thefollowing claims and that any modifications within theirscope may be used without-defp'arting from said invention. It will alsobe understood that the term brine-cooler is used as the trade name forthe apparatus and 'not to limit the same to the cooling of anyparticular fluid or substance.

I-Iaving'thus fully described my said invention, what I claim as new,and desire to secure by Letters Patent, is

l. In a refrigerating apparatus a brinecooler comprising a coil of threeor more pipes 'substantially concentrically arranged, the several pipesof the several sections being connected by iittings between theterminals of said coilwhich connect the corresponding pipes with eachother to establish lconthrough them and septrate said passage-ways onefrom the other,

fittings at the inlet end of the coil having an @inlet-opening to theouter passage, an inletlopening to the intermediate passage, and a thatI do not limit mythe coil, and the channel for the cooling agent beinglocated between said other channels and having its inlet at the end ofthe coil where the iluid to its outlet at the end where said iluid'is-turned from one channel into the other through -said bend, wherebysaid iiuid tobe cooledandthe cooling agent-are introduced at thesamebend where the cooling agent is at its iowest temperature and the duidto be cooled is at its highest temperature and` dow in the samedirection until the 4cooling agent reaches its highest temperature, fromwhence the Iii'fuid to be cooled is returned 'to the point of en-Acooling agent and is discharged Aat *the point where said lcoolingagent is at -its lowest 'temperature, substantially as set forth.
